The code is ported from downstream Codeaurora v5.4 kernel. The main difference from downstream code is the split of PCIe registers configuration from .init to .post_init, since it requires phy_power_on(). Tested on IPQ6010 based hardware. Changes in v2: * Add patch moving GEN3_RELATED macros to a common header * Drop ATU configuration from pcie-qcom * Remove local definition of common registers * Use bulk clk and reset APIs * Remove msi-parent from device-tree Baruch Siach (3): PCI: dwc: tegra: move GEN3_RELATED DBI register to common header dt-bindings: phy: qcom,qmp: Add IPQ60xx PCIe PHY bindings dt-bindings: pci: qcom: Document PCIe bindings for IPQ6018 SoC Selvam Sathappan Periakaruppan (3): PCI: qcom: add support for IPQ60xx PCIe controller phy: qcom-qmp: add QMP V2 PCIe PHY support for ipq60xx arm64: dts: ipq6018: Add pcie support .../devicetree/bindings/pci/qcom,pcie.txt | 24 +++ .../devicetree/bindings/phy/qcom,qmp-phy.yaml | 25 +++ arch/arm64/boot/dts/qcom/ipq6018.dtsi | 99 ++++++++++++ drivers/pci/controller/dwc/pcie-designware.h | 7 + drivers/pci/controller/dwc/pcie-qcom.c | 150 ++++++++++++++++++ drivers/pci/controller/dwc/pcie-tegra194.c | 6 - drivers/phy/qualcomm/phy-qcom-qmp.c | 147 +++++++++++++++++ drivers/phy/qualcomm/phy-qcom-qmp.h | 132 +++++++++++++++ 8 files changed, 584 insertions(+), 6 deletions(-)
